Profiling the Kernel
Hi *, I have a question regarding profiling the Linux kernel code during runtime (by "profile", I mean the usage of each function/module within the kernel itself). I googled and found many "system-wide" profiler such as sysprof, Oprofile, etc... I am working on an embedded system project and currently we are using an on-chip debugger which interfaces with the system through EJTAG port. All what it can provide is just a "uniform sampling" of the kernel code usage and according to the manufacturer, it is not a safe way to determine the "hot spots" within the kernel. Does anyone know about any hardware/software tool that can provide a "good" profile of the kernel code usage? Thanks in advance. Best regards, -- Mohamed A.

Hi *, I have a question regarding profiling the Linux kernel code during runtime (by profile, I mean the usage of each function/module within the kernel itself). I googled and found many system-wide profiler such as sysprof, Oprofile, etc... I am working on an embedded system project and currently we are using an on-chip debugger which interfaces with the system through EJTAG port. All what it can provide is just a uniform sampling of the kernel code usage and according to the manufacturer, it is not a safe way to determine the hot spots within the kernel.
